Product Description
1. Product Overview
Sanitary stainless steel four-way/straight-through flange sight glasses are indispensable observation devices in industrial pipeline systems. They find extensive application in the petrochemical, pharmaceutical, food, and chemical industries, providing real-time monitoring of the flow state, color changes, and various reactions of liquids, gases, or vapors. Key features include:
- Sanitary Design: With mirror-polished surfaces (Ra ≤ 0.8μm) that adhere to rigorous **GMP, 3A, and IDF standards**, these sight glasses are ideal for environments demanding the highest level of cleanliness such as those found in food and pharmaceutical sectors.
- Corrosion Resistance: Engineered from premium materials like **SUS304, 316L, 2205 duplex steel**, and optional fluoropolymer-lined/FRP materials, ensuring superior performance even in harsh chemical media.
- Structural Versatility: Available in both four-way (360° observation) and straight-through configurations, these sight glasses offer adaptability to meet a wide range of installation requirements.
2. Technical Specifications

- The four-way type allows for multi-angle monitoring, while the straight-through design is perfect for linear pipeline configurations.
2. Functional Advantages
- Leak-proof Sealing: Featuring RF, MFM flange faces, these sight glasses thrive in high-pressure environments.
- Thermal Shock Resistance: Withstands abrupt temperature shifts of ≤60°C, ensuring stability and performance.
- Easy Maintenance: Designed for quick disassembly, significantly reducing downtime and enhancing operational efficiency.
4. Applications
- Chemical Industry: Essential for monitoring corrosive media like acids and alkalis, preventing crystallization or blockages.
- Pharmaceutical & Food: Guarantees transparency and hygiene within sterile pipelines, perfect for drug solutions and dairy processes.
- Energy & Environmental: Effective for tracking high-temperature steam, oils, or wastewater in treatment systems.
5. Installation & Maintenance Guidelines
1. Installation
- Clean the glass meticulously with alcohol wipes, avoiding acidic cleaners to maintain clarity.
- Ensure bolts are tightened diagonally and evenly to prevent cracking of the glass.
- Opt for graphite gaskets for high-temperature applications or PTFE for cryogenic conditions.
2. Maintenance
- Conduct regular inspections of the glass for any signs of corrosion, increasing frequency in particularly harsh conditions.
- Replace glass with surfaces that maintain intact sealing to avoid potential leaks and ensure safety.
